Here is a step by step on how to do it:
Tools needed: a trim removal kit (bought mine locally for $9)
A Torx screwdriver set
Step 1: Hook up your VCDS and do a scan. Save it a note you mileage. In this case the VCDS scan read mileage as follows: Mileage: 54140km/33641miles; however the odometer display read 54145km. This leads me to believe the REAL mileage is stored somewhere other than the instrument cluster...so any scammer trying to alter mileage could in fact not do it.
Step 2:
2a.Go to address 17, click on coding, and write down your coding (1st line on the pop up that opens)
2b Still in address 17, click on adaptation, pull down "odometer" from the built in adaptation channels, click read, then make note of the "stored value" (in this case it was 5414).
Step 3:
Go to address 19, and make note of this installed modules, this is particularly important if you are installing a used cluster, as the used cluster will be set up for the options the old vehicle had and it might trigger some warnings if you don't have the module (ie: if the donor vehicle had air suspension, and yours doesn't - this will trigger a warning on your dash...you need to correct it by correcting module 19)
Step 4:
Remove the instrument cluster as per the pdf attachments.
A couple of tricks:
-Use a wide flat wedge trim removal tool for the wood trim, stick the wedge on the bottom edge of the wood and pry up, it'll come right off
-when removing the cluster shroud, the piece you are trying to pry off is the trim towards the instruments, not the short edge towards yourself. Just stick a butter knife in there, and pry down...it takes next to no force.
Step 5: replace the cluster, its simple and the whole process should take you less than 30 minutes. Follow the pdf and tricks I mentioned in step 4.
Step 6: Hook up your VCDS and perform the following functions:
-Go to address 17, click on adaptation, pull down odometer, the stored value will read 0. input the new value with your actual mileage that you recorded in step 2 (in this case 5414). Click test - your odometer will change to the new mileage (in this case 54,140km). Click SAVE
Still in address 17, go to coding, type in the coding you saved in step 2 above.
Go to address 19, ensure your modules match the checkboxes you saved in step 3.
THAT'S IT. You're done. All the key coding and immobilization functions reside in the kessy. All Touareg's have a kessy, some have a kessy that allows keyless entry/keyless start as well. But even base models have a kessy which recognizes your key/acts as immobilizer etc.
If you are using a used cluster, then you will NOT be able to set mileage using VCDS.
